How does Xen determines dom0 scheduling? Domains get CPU time slices
based on weight and cap but how does Xen determine the time slice for
dom0? Does dom0 preempt dom0 ever? If I put an infinite loop in dom0,
will that halt the system (as domains will never be scheduled)?
Thanks,
Lomesh

dom0 isn't treated any differently than other domains by default.
you can tweak its weight just like any other domain though.

Where is the dom0 weight and cap defined? How can I change it?

You can try:
xm sched-credit -d <domain> [ -w [=WEIGHT] | -c [CAP] ]

How can I change it in a way so that xen always set a specified weight
and cap for dom0?
